Linear scaling relationship of Néel temperature and dominant magnons in pyrochlore ruthenates
Jae Hyuck Lee, Dirk Wulferding, Junkyoung Kim +3
We present a systematic Raman spectroscopy study on a series of pyrochlore ruthenates, a system which is not yet clearly settled on its magnetic origin and structure. Apart from th…
Stripe Symmetry of Short-range Charge Density Waves in Cuprate Superconductors
Jaewon Choi, Jiemin Li, Abhishek Nag +12
The omnipresence of charge density waves (CDWs) across almost all cuprate families underpins a common organizing principle. However, a longstanding debate of whether its spatial sy…
Collective magnetic Higgs excitation in a pyrochlore ruthenate
Dirk Wulferding, Junkyeong Kim, Mi Kyung Kim +13
The emergence of scalar Higgs-type amplitude modes in systems where symmetry is spontaneously broken has been a highly successful, paradigmatic description of phase transitions, wi…
Electron-hole symmetry in quasiparticle spectral weight of cuprates observed via infrared and photoemission spectroscopy
Myounghoon Lee, Dongjoon Song, Yu-Seong Seo +4
We performed an optical spectroscopy study on single crystals of PrLaCeCuO (PLCCO) to revisit the electron-hole asymmetry, which has been understood as a…
Kondo interaction in FeTe and its potential role in the magnetic order
Younsik Kim, Minsoo Kim, Min-Seok Kim +16
Finding d-electron heavy fermion (HF) states has been an important topic as the diversity in d-electron materials can lead to many exotic Kondo effect-related phenomena or new stat…
Correlation effects obtained from optical spectra of Fe-pnictides using an extended Drude-Lorentz model analysis
Seokbae Lee, Yu-Seong Seo, Seulki Roh +3
We introduce an analysis model, an extended Drude-Lorentz model, and apply it to Fe-pnictide systems to extract their electron-boson spectral density functions (or correlation spec…
